SHUTTLE GUARD FOR LOOMS.

Specification of Letters Patent.

Patented Feb. 14, 1922.

Application filed September 26, 1921. Serial No. 503,413.

and State of Pennsylvania, have invented certain new and usefulImprovements in Shuttle Guards for Looms, of which the following is aspecification.

This invention relates to looms of the ordinary type and has for itsobject the improvement in shuttle traps or guards for the same, beingadapted in the event of a shuttle flying out ofthe warp to confine theshuttle in the trap or guard and thus safe guard the operator orbystander.

The various features of the invention will be hereinafter more fullydescribed in connection with the accompanying drawing, in which y Figure1 is a front elevation of a hand rail and lay beam of a loom with theshuttle guard attached to the former.

Figure 2 is a section taken at right angles to Figure 1 and in a planeindicated by line 2-2 of said figure showing the guard in a raised andnormal position.

Figure 3 is a sectional view of hand rail and trap with inwardly openingshutters.

Figure 4; is a top plan view of the shutters as attached to the trap.

Figure 5 is a sectional view of the shut ters, holder, and spring.

Referring to the drawing, 1 indicates the hand rail and 2 the lay beamof an ordinary loom. Permanently secured to the top of the hand rail 1is a metal strip 3; 4: indicates a metallic strip covering the frontface of the hand rail 1, being hinged to the strip 3 at 5. Secured tothe strip 4 in any suitable way are a plurality of inverted U- shapedholders 6 on the inner face of which are secured a plurality of spacedparallel rods '7 forming a cage. The rods 7 at the ends of the cageconverge and are held in place by solid inverted U-shaped holders 8closing the ends of the cage.

In the lowermost rods of the cage are incompleted grooves in whichoperate and fit straps 9, one end of which abuts against the shoulders10 and the other ends are suitably secured to shutters 11. Springs 12surround the lowermost rods of the cage and engage the tops of theshutters 11, the purpose of which is to hold the shutters in theirclosed positions, the shutters opening in ward. The guard as hereindescribed may be applied to any form of loom in which a shuttle is used.

In practice it will be observed that in the event of the shuttle flyingout of the warp (shown by dotted lines in Figure 1) it will strike thebottom of the shutters 11 at an angle as shown by dotted lines, passthrough the said shutters, the upper end striking the top of the cage orguard and deflected into a horizontal position inside the cage on top ofthe shutters. The guard can then be raised to the position shown inFigure 2, the shutters opened inward and the shuttle removed. From thisit follows that the shuttle is effectually prevented from forciblyleaving the loom and injuring an operator or bystander as frequentlyhappens when no means is provided for retaining the shuttle in the loom.

lVhat I claim as new and desire to secure by Letters Patent, is

1. A shuttle trap for looms comprising a semi tubular structure havingclosed ends and arranged over the lay beam, said structure having in itslower side a plurality of shutters adapted to open inwardly.

2. A. shuttle trap for looms comprising a semi tubular structure havingclosed ends and arranged. over the lay beam, said structure having inits lower side a plurality of relatively short shutters adapted to openin wardly.

3. .A. shuttle trap for looms comprising a semi tubular structure havingclosed ends and arranged over the lay beam, said structure having in itslower side a plurality of two opposed series shutters adapted toopeninwardly.

4. A shuttle trap for looms comprising a semi tubular structure havingclosed ends and arranged over the lay beam, said structure having in itslower side a plurality of shutters adapted to open inwardly, means forholding said shutters in place.
